SUMMARY
This discussion focuses on evaluating a triangular fermion loop in quantum field theory (QFT), specifically involving a scalar field decaying into a fermion-antifermion pair that produces two photons. The process involves tracing back from the photon vertices using vertex factors and propagators. Participants highlight the importance of considering the chiral anomaly, which introduces complexities in the integral evaluation. For comprehensive guidance, consulting advanced QFT textbooks is recommended.
